Are the symptoms *exactly* the same with the new code?

This doesn't prove anything.  Linux uses an entirely different library
with a different implementation of `sscanf'.  It could mean that
DJGPP's version has a bug that reveals itself in your case, but it
also could mean that the bugs in your code manifest themselves in a
different manner in these two environments.

If you cannot figure this out, please post a complete short program
that can be compiled and debugged, and which exhibits this behavior.
Then someone will probably find the problem.
